Exporting properties and references from a sub-project to its parent project
This is something I struggled with in NetBeans-generated Java projects. I wanted to permit build scripts to call dependencies recursively without reentering any dependencies during a single build (and maintaining locality of information: a script knows only about its own direct dependencies). The natural idea is to just set a property mentioning ${basedir} when building one project and exit early if it is already set, but this does not work since properties set in a child cannot be propagated to the parent. The ugly workaround I found was to create a properties file in a build dir when building the topmost project, passing its location to children, and loading and saving it from each build. Obviously this involves otherwise unnecessary file I/O and is very hard to follow, especially considering that it is tricky to load properties in an isolated namespace in Ant, and "if (...) return;" is impossible from the dependency so a subbuild can be skipped only from the depending script.
